A dehumidifier is a home appliance that helps control the humidity in the house and removes excess water from the air. If you live in a place with high humidity or where it does not get too cold during winter, then having a dehumidifier at home will be useful for you.

Types of Dehumidifiers
Dehumidifiers work on different ways to bring down the level of humidity in your house. There are two types of dehumidifiers: Desiccant and Refrigerant. Desiccant dehumidifiers use desiccants such as silica gel to draw the excess moisture from the air whereas refrigerant dehumidifiers use chemical processes and evaporative cooling methods to reduce humidity in homes and buildings. This article deals with how refrigerant dehumidifiers work and the best portable dehumidifier reviews.
How Refrigerant Dehumidifiers Work?
Refrigerant dehumidifiers are specially designed to remove excess humidity from your home or office, especially during winters when the outside temperature is not very low. During winter, there is high amount of water vapour in the air due to excessive heating indoors. This causes condensation on windows which can also damage furniture and other things around. Hence, it becomes important to keep your indoor temperature low so that you don’t have these problems during wintertime. A refrigerant dehumidifier does this job for you by removing water vapour from the air . It has an effective self-evaporating system that keeps away excess humidity and moisture from your house, and you can read about the best dehumidifiers for basement here.
Refrigerant dehumidifiers use a refrigeration process to extract water from the air. When water is evaporated, it absorbs energy required to vaporize the liquid into gaseous form. This energy is known as latent heat of fusion. In other words, when water (liquid state) changes its state to steam (gaseous state), it gives off heat which saves the indoor temperature because the heat has been absorbed by the water vapour in the air. So if there is too much humidity inside your home or office, then having a refrigerant dehumidifier will reduce it to a considerable extent and save a lot of energy too.
Most refrigerant type dehumidifiers use the compressor-based technology to absorb water vapour from the air passing through a wet evaporator coil. The process uses a combination of cold air and hot air which makes the water droplets on the evaporator coils condensate as liquid form. A fan or some other mechanism is used to draw out this liquid from the base of the unit. Various factors such as temperature, pressure, etc influence both evaporation and condensation processes in your dehumidifier. Since these processes are complex, manufacturers tend to provide only rough estimates about their products’ maximum moisture capacity (how much moisture they can extract). Here we have reviewed top 10 portable dehumidifiers of 2018.
How an Evaporative Dehumidifier Works?
Evaporative dehumidifiers work on a simple principle: they let dry air pass through moist pads which absorb the moisture from the air and removes it as liquid form. These types of dehumidifiers are also known as “Swamp Coolers” because they reduce the level of humidity by cooling down hot, dry air thereby creating comfortable living conditions during summertime. Swamp coolers work similar to refrigerant type dehumidifiers; still there are some differences that make them suitable for use indoors or outdoors. The pros and cons of evaporative vs refrigerant dehumidifiers will you decide which one is better.

How to Remove Humidity from Your House
In the early fall, people generally use their central heating system for removing humidity from low-level areas in their home. But when you have a house with high ceilings or an especially big basement, then it becomes difficult to remove excess humidity all at once. Sometimes due to cold weather outside it’s too risky to open windows in your house because if not properly sealed in colder zones, these windows can cause damage to your furniture and other stuff around in the form of moisture and condensation which can lead mold growth. Replacing old windows is also not an option because they are expensive. As a solution to this problem, many people prefer portable dehumidifiers that can provide efficient results in small spaces like basements, attics or home offices.
